ANNULAB ROLLER-BEARING.

Patented May 23, 1911.

Application filed August 5, 1908. Serial Ho. 447,037.

- One object of the present invention is to provide an annular roller bearing adapted surface 2,- and an inner edge with an out-' as to size and shape for re lacing annular ball bearings and which shal be satisfactory, durable and eificient under all circumstances of use even when exposed to relatively severe end thrust.

' The invention will be claimd at the end hereof but will be first described in connec-.

tion with the embodiment of it chosen for illustration in the accompanying drawings in which- Figure 1, is an end view of an. annular roller bearing embodying features of the invention and having a ort'ion .of the inner ring removed. Fig. 2,-1s a central sectional view taken on the line 2-2, of Fig. 1, and Fig. 3, is a sectional view showing two of the annular roller bearings 'operatively arranged.

In the drawings 1, is an inner ring provided externally with a conical roller race wardly rojecting flange 3 havin an outwardly t ii eveled abutment or wor ng side 4, the purpose and function of which will be hereinafter described.

5, is an outer ring concentric with the inner rin and provided internally with a conical ro ler race surface 6.

7, are conical rollers arranged between the races -and having their larger ends chamfered to conform to and ride on the outwardly beveled working side of the flan e which extends well out over the larger en s of the rollers. End thrust is referred to the outwardly beveled side 4, ofthe flange 3, and the ends 8, of the rollers and to the conical surface 6, and the faces of the rollers according to the directionof the thrust.

The described construction is well adapted to resist such thrust.

There is a cage consisting of connecting rods 9, and of large and small conical rings 10 and 11, each having confronting projections 12, provided with concave side walls constituting roller pockets. The ring 10, is internally cut away or rabbeted as at 13, to expose the larger ends of the rollers and receive the flan e 3, on the inner cone.

The roller caring as a whole is compact and adapted for use interchangeabl with so-calledannular ball bearings, its rol ers are free in the sense that they are not mounted on pivot pins andits construction is such that it is well adapted to resist end thrust without undue friction or grindin while at the same time to act as a radia thrust bearing.

What I claim is:

An annular roller bearing comprising an inner ring provided with a conical roller ra'ce surface and. at one edge with'an-outwardly projectin flange having an outwardly beveled a utment or working side, an outer rin concentric with the inner ring and provide internally with a conical roller race surface, conical rollers arranged between the races and having their larger ends chamfercd to conform to and ride on the outwardly beveled working side of '-the flange, and a cage consistin of connecting rods and of large and smal conical rings each having confronting projections pro- SAMUEL s.
